BLOW-GUN.

SPECIFICATION forming part of Letters Patent No. 477,322, dated J' une21, 1892.

Application filed July 30, 1891. Serial No. 401,202. (No model.)

To all whom, t may concern:

Be it known that I, WILLIAM MITcHELMonn BUNSEN, a citizen of the UnitedStates, residing at Galesville, in the county of Trempealean and Stateof Wisconsin, have invented a new and useful Blow-Gun,of which thefollowing is a specification.

This invention relates to improvements in toy air-guns, and to thatparticular kind in lo which the missile is ejected by means ofcompressed air forced through a tube communieating with the mouth of theoperator.

The objects of my invention are to provide a gun of the above class andof an extremely I5 economie and simple construction, that is easy toload, andwhen loaded is automatically returned to a position ready forfiring.

Other objects and advantages of the invention will appear in thefollowing description,

2o and the novel features thereof will be particularly pointed out inthe claims.

Referring to the drawings, ligure l is a perspective of a gunconstructed in accordance with my invention. Fig. 2 is a verticallongitudinal section. Fig. 3 is a detailin perspective of thebarrel-locking yoke and spring. Fig. 4 is a detail of the dart ormissile.

Like numerals of reference indicate like parts in all the gures of thedrawings.

The stock of the gun comprises the usual butt 1, which at its front endis merged into the reduced grip 2, and beyond the same into the fore-arm3, which latter has its upper front portion cut away to form the block4, which is provided at its front edge with an inclined face 5. v

6 denotes the barrel, which lits upon the cutaway portion of thefore-arm, and at its rear end is inclined at 7 to correspond with theinclined face 5 of the block, said rear end or breech of the barrelbeing adapted to fit snugly against said block. Upon its under side thebarrel is provided with a continuation S of the fore-arm, the same beinglocated v in front of' said fore-arm and connected at their meetingedges by means of a simple hinge 9, whereby the barrel may be throwninto and out of alignment with the remainder of the gun for the purposeo f exposing its 5o breech above the block 4.

The barrel is provided with the usual bore l0, which is continued by anair-passage 1l, formed in the grip 2 and block 4, and laterally branchedat the rear end of the grip, and has connected thereto a flexible rubbertube 12, which extends from the grip a suflicient distance rearwardly soas to reach the mouth of the user when the gun is at the shoulder and isthere provided with a suitable mouthpiece 13.

The rear end of the barrel is embraced b v an oblong yoke or bail 14,which is pivoted to the barrel at diametrically-opposite sides, as at15, and its terminals extend below the barrel, embracing the fore-arm 3loosely, and by o5 a pin 16 is pivotally connected with an eye 17,formed at the front end of a spring-wire 18. The wire 18 is rearwardlycurved substanti-ally parallel with the grip to form a grip portion 19and in rear of the same is 7c coiled, as at 20, and inwardly disposed,terminating at a point 2l, driven into the grip 2 of the stock.

The dart or missile employed in connection with the gun, as illustratedin Fig. 4 of the 75 drawings, comprises a cylindrical body portion 22 ofwood, provided atits front end with a point or suitable head 23, and atits rear end has secured thereto by a tack, glue, or other means a smalldisk 24 of cloth, against 8L which the compressed air may impact.

In operation the user grasps the grip portion of the stock and passeshis lingers under the wire, pressing the same toward the grip portion,and thus serves to press the barrel upwardly or swing its breech awayfrom and out of `alignment with the air-passage in the grip and block.The dart is now inserted in the breech and the spring released, the sameserving to return the barrel to a closed posi- 9o tion, in which thebore of the same and the air-passage 11 align and communicate. The gunis now ready for tiring, and in accomplishing the same it is brought tothe shoulder in the usual manner, the head lowered so as to permit theeye to sight along the,barrel, and when in such position the mouth ofthe user will be directly opposite the mouthpiece 13.

It now simply remains to give a strong blow into the mouthpiece and theair compressed roo in the air-passage 11 in rear of the dart serves toeject the dart with considerable force.

l. In a toy gun of the class described, thel combination, With the stockcomprising the grip, the fore-arm, and the block having an inclinedfront face formed at the rear end of the fore-arm, the barrel hinged atits under side to the fore-arm and at its rear end adapted to closesnugly against the block, the block and grip being provided with anair-passage zo communicatingwith thebarrehandatube connected at the rearend ot' the air-passage and terminating in a mouthpiece, of aspring-wire loosely connected to the barrel, rearwardly extended underthe grip, and terminating in z5 a coil, and at its end forwardlydisposed and secured to the grip of the gun, substantially as specified.2. In a toy gun of the class described, the combination, with the stockcomprising the 3o grip, the fore-arm, and the block having an inclinedfront face formed at the rear end of the fore-arm, the barrel hinged atits under side to the fore-arm and at its rear end adapted to closesnugly against the block, the block and grip being provided with anair-passage communicating with the barrel, and atube connected at therear end of the air-passage and terminating in amouthpiece, of a yokeloosely embracing and pivoted to the rear end of the 4o barrel, aspring-Wire loosely connected to the extended end of the yoke,rearwardly extended and terminating in a coil, and interminating in amouthpiece 13, of the bar-V rel inclined at its rear end to it the faceof the block and having its bore communicating with that of the blockand grip and provided upon its under side With an extension of thefore-arm, the hinge connecting the extension with the fore-arm,theelongated yoke 14, embracing the barrel and fore-arm and pivoted at l5to diametrically-opposite sides of the barrel, and the spring-Wire bentto form the grip extending parallel with the grip of the gun, having itsfront end terminating in an eye pivoted to the yoke and at its rear endcoiled to form spring-coils and beyond the same terminating in apointdriven in the under side of the grip of the gun, substantially asspecified.

4. In a toy gun, the combination, Witlrthe stock comprising the fore-armand the block, of a barrel hinged to the fore-arm and adapted to closeagainst the block, a pneumatic tube leading to the barrel, a yokeembracing the barrel and depending below the fore-arm,and a bowed springhaving one end connected to the stock and the other to the yoke,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in' presence of two witnesses.
